EDM and Injection Molding Tooling  

 The use of EDM in injection molding tooling is so essential that it is almost impossible to imagine a modern shop without and EDM machine. Many of today's products simply could not be produced without it. Think of all the cell phones, calculators, IPods, cameras, medical devices and the endless amounts of high tech equipment that are made out of plastic!

Besides it's us in plastic injection mold making, EDM is used for the precision machining of medical parts, aerospace parts, and other highly specialized products. Wire EDM has also completely changed the way molds are made, as well as other specialized parts.

You can also find educational material that attempts to explain this rather mysterious process. Not so long ago, it was as much black art as science. Today, however, much of the mystery is removed due to CNC controls.

Most shops send their operators to classes put on by the manufacturer of their EDM machine. It is foolish to invest so much money in a machine and skimp on the training! But it happens all the time.

What about EDM and stress?

EDM is quite a stressful occupation, to put it mildly. It may not appear difficult, but the stress levels can be exhausting. Nearly every mold component that is EDM'd is in the final stages of manufacturing. The slightest mistake can become very costly, very quickly.

There is nothing quite like the feeling of coming to work in the morning and seeing your supervisor leaning over the EDM machine staring at your workpiece. Then you find out that you had mixed up two locations and the completely finished cavity block is now completely useless! Aaagggghhh!

There are various methods of managing this stress, one of the most effective is a program developed by Mind Tools.

EDM Tooling

Today, every progressive company uses at least one highly sophisticated system of EDM tooling. This tooling is essential for manufacturing, inspection, and the actual machining.

Electrode Materials

Graphite and copper are the dominate materials, with various other materials meeting the needs for special applications.

Dielectric Fluids

Dielectric fluid is a necessary part of the EDM process. As new types of fluids are developed, higher precision is possible, finer finishes are attainable, and the environmental impact is reduced. An added benefit is that your operators won't smell like diesel fuel anymore either!
